  2. 1. Metaphyseal Fracture Healing

    Author : Olof Sandberg; Per Aspenberg; Aaron Schindeler; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Most of what is known about fracture healing comes from studies of shaft fractures in long bones. In contrast, patients more often have fractures closer to the ends (metaphyses). Here most bone tissue has a spongy, cancellous structure different from the compact bone of the shaft. READ MORE

  4. 2. Norway spruce heartwood : properties related to outdoor use

    Author : Karin Sandberg; Lars-Olof Nilsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : Degradation of wood is a complex problem dependent on many parameters, but especially the presence of excessive amounts of water causes many problems.The objective of this work was to study the influence of various parameters on water absorption and desorption in Norway spruce (Picea abies (L.) Karst). READ MORE

  5. 3. Finite element simulation of airbag deployment and optimization in crashworthiness design

    Author : Per-Olof Marklund; Göran Sandberg; Linköpings universitet; []
    Keywords : ;

    Abstract : The passive safety of cars is of uttermost importance for the automotive industry. To improve the safety of cars, computer simulations of the vehicle and occupant system by the Finite Element Method (FEM), have become an industry standard tool. READ MORE

  6. 4. SAWING STRATEGIES FOR TROPICAL HARDWOOD SPECIES : Simulation studies based on industrial conditions of Mozambique

    Author : Pedro Ah Shenga; Dick Sandberg; Olof Broman; Mats Nylinder; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sawing strategies; tropical hardwood species; simulation; volume yield; log grading; umbila; jambirre; Träteknik; Wood Science and Engineering;

    Abstract : The harvesting of Mozambique tropical hardwood species is considerable higher than the natural regrowth in the forest and the stock is decreasing drastically. Therefore, it is important to improve the material recovery when the wood is refined (i.e., in sawing and further refinement to products such as joineries, furniture etc. READ MORE

  7. 5. Machine Learning for Appearance Grading of Sawn Timber using Cameras and X-ray Computed Tomography

    Author : Linus Olofsson; Dick Sandberg; Olof Broman; Magnus Fredriksson; Johan Skog; Erkki Verkasalo; Luleå tekniska universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Träteknik; Wood Science and Engineering;

    Abstract : This doctoral thesis deals with a new approach for the appearance grading of sawn timber adapted to the requirements of modern sawmilling industries and timber market situations. Appearance grading of sawn timber allows wood products to be made with a specific visual style due to wood features such as knots. READ MORE
